This kit includes the minimum parts you need to make some serious power! No matter if you ride trails, mud, or dunes, we know your Ranger needs more power. From the factory, they are sluggish because of the heavy clutching and ECU tune that does not allow full RPM or even full throttle. We fix that by adding our performance tune which opens the throttle 100% and removes torque limiters. It also removes the soft and hard rev limit so we can increase peak RPM to between 8000-8500 where much more power is made. Fuel and timing adjustments are also made to improve overall performance. Our Stage 1 clutch kit includes our Goldstar magnetic adjustable primary weights and a custom BMP primary spring. These simple clutch changes allow the motor to rev much higher than factory to where the real power is made. For even better results, purchase our Stage 1 Bolt-On Performer kit which upgrades your exhaust and secondary clutch also.

**We also highly recommend welding your spider nut on the primary clutch** This is a fairly simple modification especially when the clutch is already apart to install the weights. Due to the higher RPM of this tune, some spider nuts have had issues coming loose. Please see the last image showing this modification performed.
